Based on the actual recovery situation, it is usually divided into several stages. First of all, unilateral cleft lip and palate repair surgery is generally performed on children between 3 and 6 months old, while bilateral cleft lip and palate surgery is usually performed on children between 6 and 12 months old. Some children can undergo surgery after birth. If it is cleft palate repair surgery, it is mostly performed when the child is 12-18 months old. The child's pronunciation status should be checked within six months after the operation, and early voice training should be carried out. If the pronunciation has not improved significantly, secondary pharyngoplasty can be considered by about 4-5 years old. For patients with severe cleft lip and palate, 9-11 years old is the ideal age for dental restoration. After the growth and development is completed (males are 17 years old and females are 15 years old), a second plastic surgery is performed. The scars will fade after surgery and there will be no obvious scars.
